1991 K75S replacement radiator fan

[ecd3]

Does anyone have a suggestion for replacing the radiator fan. I have tried the Brighton Racing Products for their Spal puller fan but they don't return emails. If so what size fan and did you have any problems trying to get information from them.  My current fan will not turn freely. I have contacted them twice and not gotten a response back.
thanks ,

Not sure if your 91S model is the same as my 86C, but I just replaced my failed motor with one from BeemerBoneyard. They claim this motor fits all K75/100/1100.

Seconds for Beemer Boneyard. swapped out the fan motor about a week ago before leaving on a cross country jaunt. last minute thing after I got a dead fan from an ebay dismantler who did not want to give me my miney back. Boneyard got me the motor in about 3 days.
